| Abstract: |
The present invention relates to a plum tree and more particularly to a new and distinct variety broadly characterized by a medium size, medium vigorous, hardy, productive, and regular bearing tree, which requires a pollinator. The fruit matures under the ecological conditions described in the latter part of June, with first picking on June 19, 1989, and is uniformly large in size, clingstone in type, very dark purplish red in skin color, smooth in surface appearance, attractive in shape, sweet in flavor, and exceptionally firm in texture, resulting in excellent quality for keeping and shipping. The variety was developed as a hybridized seedling from the selected seed parent, Red Beaut (U.S. Plant Pat. No. 2,539), and an unnamed seedling as the selected pollen parent. |
| Claim: |
We claim:
1. A new and distinct variety of plum tree, substantially as illustrated and described, which matures at nearly the same time as Santa Rosa, unpatented, but is distinguished therefromand an improvement thereon by producing fruit that is larger in size, much firmer in texture, darker in skin color at shipping ripeness, and axially compressed in shape. |
| Description: |
BACKGROUND OF THE NEWVARIETY
In a continuing effort to improve the quality of shipping fruits, we, the inventors, typically hybridize a large number of nectarine, peach, plum, apricot, and cherry seedlings each year. The present invention relates to a new and distinctvariety of plum tree, which has been denominated varietally as "Purple Majesty". The present variety was hybridized by us in 1982, and the resulting seedling was planted in a cultivated area of our experimental orchard at Bradford Farms near Le Grand,Calif. in Merced County (San Joaquin Valley). Specifically, the hybridized seedling was originated by using Red Beaut (U.S. Plant Pat. No. 2,539) as the selected seed parent and an unnamed seedling as the selected pollen parent. Subsequent toorigination of the present variety of plum tree, we asexually reproduced it by budding and grafting, and such reproduction of plant and fruit characteristics were true to the original plant in all respects.
The present variety produces fruit that matures at nearly the same time as Santa Rosa, unpatented, but is distinguished from that variety by being self-sterile instead of self-fertile and by producing fruit that is larger in size, firmer intexture, axially compressed in shape, and darker in skin color at shipping ripeness.
The present variety is similar to its selected seed parent, Red Beaut (U.S. Plant Pat. No. 2,539), by being self-sterile and by producing fruit that is smooth in surface appearance and very firm in texture, but is distinguished therefrom byproducing fruit that ripens twenty-one days later, that is very dark reddish purple in skin color instead of red, that is much larger in size, and that is much sweeter in flavor.
DRAWING
The accompanying photograph exhibits three whole fruits positioned to display the characteristics of the skin color and form; one fruit sliced to reveal the flesh; a clean dry stone; and a branch with leaves, all typical of the subject variety.
POMOLOGICAL CHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of plum tree, the following has been observed under the ecological conditions prevailing at the experimental orchard of the inventors near LeGrand, Merced County (San Joaquin Valley), Calif.
